How to Install a Hard Drive

Knowing how to install a hard drive can save you a great deal of time and money when your old hard drive fails or needs an upgrade. Whether you need to install a new hard drive to replace an older one or need to install a new hard drive for additional disk space, installing a hard drive is a fairly quick and simple task.

1. Read the manual. Before purchasing a new hard drive, make sure you're familiar with your computer's manual so that you understand what interfaces your motherboard supports. If you're installing an additional hard drive, you may have purchased software that you'll need to run prior to installing the hard drive. Your new hard drive should have a manual that will let you know if you need to run the software.

2. Power down. As with any repair to an electrical device, you'll need to power down your computer. Close all programs, power down your computer, turn off the power switch on the back of the computer and unplug the computer.

3. Stop static. Put on an antistatic wrist strap. This strap can keep static from damaging any of your computer's parts as you work.

4. Open the case. Once your computer is powered down, you can open the case to install the hard drive. Depending on the make and model of your computer, you can access the inside of your machine through a side panel or by removing the side of the case. Either way, this process usually involves removing a few screws.

5. Find the hard drive bays. You can usually find them in the front of the computer. There should be an empty spot for you to install your new hard drive near the existing hard drive.

6. Mount the hard drive. Your new hard drive will either snap in and out of the hard drive bay or need to be mounted with screws that came with your hard drive. If you need to utilize the screws, line up the screws with the holes in your hard drive, and tighten them down.

7. Connect the cable. Once the hard drive is mounted, find the additional power connecter, usually a ribbon cable, and connect it to the hard drive. Next, connect the interface ribbon cable to your hard drive.

8. Reassemble the computer, and check the results. Replace the side panel, screwing it back on, and power up your system. Either install a new operating system if you are starting from scratch, or check to see if your current main hard drive is recognizing the new one
